Steps Using Derivative Rule for Sum

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is $0$. The derivative of $ax^{n}$ is $nax^{n-1}$.

$$3y^{3-1}-5y^{1-1}$$

Subtract $1$ from $3$.

$$3y^{2}-5y^{1-1}$$

Subtract $1$ from $1$.

$$3y^{2}-5y^{0}$$

For any term $t$ except $0$, $t^{0}=1$.

$$3y^{2}-5$$
